My invention relates to manifolding ma chines of the type wherein the webs of paper are fed by means of one or more pin wheels, the pins of which engage rows of apertures in a plurality of webs of paper and advance them through the machine.

In manifolding machine .of the pin wheel feed type, the primary requisite is that the several webs of paper be free for shifting about while the pins are engaging the holes 1 therein and jogging the webs forward. It is thus desirable to hold the webs of paper down on the pins in such a way that the least possible opposition to their movement is set 5 up, and further it is-desirable to firmly grasp the webs of paper at the end of feeding operations to the end that the careless operator does not jerk the paper out from the machine in the act of tearing off the issued sections. In the original patent on the pin wheel feed manifolding machine, to. wit: T. F.

Schir'mer No. 940,481, dated November 16,

1909', there was shown a pressure roller mounted over the drum which carried the feed pin wheels. This roller was lifted by cams during the feeding operation and lowered to grasp the paper at the end of. the feeding operation.

Such rollers are expensive, and require much more labor than a simple plate stamping, and among other objects of my invention is the provision of a stamping in the form of a cross bar or plate which is shaped to accomplish the functions of the Schirmer roller, and at the same time to accomplish a more effective clamping during the tea-ring off operation. I

My invention also relates to manifolders in which the frame of the machine is entirely enclosed except for exposure of the parts for manipulation and writing, by means of a housing or cabinet.

It is the object in this connection to provide means whereby the mechanism for maintainmg the paper on the pins is operated and controlled from outside of the cabinet, and 4 wherein the cabinet has deflecting means therein to pushthe stop pins for the o erating handle operation out of the way uring the act of moving the cabinet, over the machine, and removing it therefrom.

I accomplish the objects above stated and other advantages to be noted by that certain construction and arrangement of parts-to be hereinafter more specifically pointed out and claimed.

The machine is erected on a suitable base 1, and has side frames 2, 2, and paper rolls 3 mounted on spindles 4. On the feed shaft 5 are pin wheels having ins 6 radial thereof, and also having cams? with small depressions 8 therein. Hinged at 9 are the arms of the Writing table 10 of the machine, which table extends forward over the pins and ter-. minates at 10 just beyond the point where the pins will contact with the paper. The table element is provided with openings 10 for clearing the pins and is cut away at the sides to expose the cams. Small cars 10 are located just ahead. of the opemngs 10 to impart a lifting action to the paper and thus not only keep a proper relation to the pin wheels, but arrest the clamping between feedlng operations.

The writing table has idlers 13 between its arms for passage of the webs of paper from the several rolls.

Mounted at the issue end of the machine is a stripper plate or guide plate 14, which is hinged at 15 and swings down to a position resting on the side frames to a point substantially abutting the end of the writing table. This plate may, however, be secured in other ways and may be on the cabinet. It is cut out at 16 for passage of a record web, which is wound up on a roll 17 This plate is cut out to clear the mounting arms of the pressure bar element, which will be described below.

On the feed shaft is a handle 18, same hav- 20 ing a detachable hub 19, so that the handle can be mounted after the cabinet is in place.

A small housing or bracket 20 is secured to the side frame adjacent the handle position,

and between this bracket and the frames are set a pair of stop pins 21, each pin being provided with a shoulder at 22, and springs 23 wound around the pins and pressing on the shoulders, tend to hold the pins in a position to block the path of the handle 18. As shown in Figures land 9, the handle has two lugs 18 and 18, of which the lug 18 misses the upper pin 21, during the feeding or counterclockwise movement, and then strikes and stops against the lower or second pin. The lug 18 in its arc of movement with the handle rides over the upper pin 21, and comes to rest behind this pin so that the handle can not be reversely turned. A small trigger 24 on the handle is used to depress the forward and lower stop pin 21, and the back stop pin must be pushed in by hand. The trigger 24 has a nose 24 which engages the stop pin alongside of the lug 18.

An ear 24 on the handle serves as a support to which the trigger is mounted so as to swing in the plane of the edge of the handle. A

spring 24 holds the trigger with the nose 24 out of the way of the stop pins until it is depressed.

The stop device is provided in order to limit the cycles of movement of the feed devices to one complete revolution at a time. p

The cabinet 25 is hinged by means of the special hingedevices 26 shown in the patent of John Q. Sherman and applicant, dated April 1, 1924, No. 1,480,014. It has a'clearance opening 27 for exposing the writing table and has a hole 28 for, exposing the end.

of the feed shaft for mounting the handle hub thereon.

In order to expose the stop pins the cabinet is provided with an opening 29. The side wall of the cabinet is formed witha spherical shaped projection 30, located so that when the 5 cabinet is lowered, thisprojection will strike the pins and force them in. In Figure 5 the inside of the cabinet is to the left.

The lower wall surrounding the opening 29 is formed with a spherical projection 31, which when the cabinet is lifted will engage and force inwardly the two stop pins.

The cabinet opening 27 extends to the edge 32 just forwardly of the paper feeding devices. This opening gives clearance for the pressure bar element, and the plate 14 has two slots 33 and 34, which give clearance for the arms by means ofwhich the said pressure bar element is mounted, and for the triggerby which the element may be held out of the way of setting up the paper forms.

Mounted on a shaft 35 across the machine frame, area pair of arms 36 which arms extend up through slots in the stripper and the cabinet (when the latter is in place). The shaft 35 may be spring impelled by means of a coiled spring 37 about the shaft, which spring is tied to a rod 38 forming one of the machine frame braces.

The pressure element is mounted on the arms 36, and instead of being formed as a roller, is formed up of sheet metal. The bar has a central depressed rounded portion 39 and higher edges 40, 40, which are screwed to the two arms. It also has pin clearance slots 39.

On the forward edge of the bar is secured the tear-01f blade 41 which lies in close proximity with the stripper or guide plate 14.

Nearthe ends of the bar the rounded or head portion 39 is cut away and the ends are turned up, providing a space in which two small rollers 42 may be mounted, said rollers having mounting pins 43, set into the turned up ends. The rollers 42 ride on the two cams. In operation the paper is brought forward over the writing table and the forms arranged with the underneath web, where used as a record strip, being led through the slot in the plate 14 and down over the curved end 10 of the plate 10. This plate or whatever means is used to define the path of the record web receives it after it passes through the slot in the plate 14.

During this operation the arms supporting the pressure bar element are raised upwardly.

This is done by lifting up on the car 45 on.

one of the arms and when the arms are raised the trigger 46, pivoted to the side of the machine will engage behind the nose 47 on the bar supporting arm adjacent thereto.

When the webs are arranged in alignment and set down over the pins where they pass up through the slots 10 in the writing table,

the pressure element is lowered, by releasing the trigger. The cabinet is then lowered in place, automatically throwing the stop pins out of the way. The handle is then mounted over the feed shaft, and will be set so that it is in engagement with the rearward stop pm. V

When the feed handle revolved the cams will elevate the pressure element, and the along At the end of each complete revolution of the feed handle, the cams will permit the pressure element to drop which will clamp the paper tightly, and will bring the tear ofi blade into close engagement with the paper.

The operator can then tear off sections of the webs. It will not be necessary to raise the cabinet, should the paper webs get out of registry, and need adjustment for any reason, since the cabinet clears the pressure element, thus permitting its manipulation whether the cabinet is opened or closed.

I have not described the carbon paper devices, nor numerous 'details of manifolding the issued machines of the type in question as these are familiar in in the art. I

The relation of the several paper supporting and guiding plates may be varied, without altering the essentials of my invention which are the novel pressure element, to-

general practice to those skilled gether with the fact that same can be cleared by the cabinet. Also the automatic forcing out ,of the pins as the cabinet is raised is a useful and novel feature of this invention. In former instance of cabinet type manifolding machines, using the pressure roller of the Schirmer patent, the cabinet had to be specially formed to clear the roller, and a housing and journals for the roller had to be provided on the frame.

Having thus described my invention. what I claim as new and desire to secure by Letters Patent, is 2- I 1.
